It's not only Americans. In my history classes in an Argentine high school my professor was a serious conspiracy theories who taught how, among other things, the 9/11 attacks were engineered by the US government for world domination, George Bush wanted to buy southern Argentina to steal our freshwater reserves, and Cuba found the "natural" cure for cancer (but of course the US government doesn't allow it to be exported). I heard these conspiracies coming from otherwise smart people all the time. The issue here is that we have an entire generation that was raised in an environment where having stupid beliefs didn't matter, since news came from mostly "expert" sources, which is now living in a world where a big part of the information you give and receive comes from sites like Facebook or Twitter. If it's an education problem, it's unsolvable: you can't easily teach 50 year old the way they thought about media their entire life was wrong.
